Overview

iFlight Albatross V2.1 is a 5.8GHz FPV antenna with a rugged hexagonal housing and right-angle design for convenient fixation. It uses upgraded welding technology to improve reliability, and is designed to provide consistent antenna gain for stable FPV performance. For DJI Digital FPV, use RP-SMA LHCP (Left Hand Polarization); the default air unit antennas are LHCP and the goggles antennas are LHCP, so both sides must match.

Changelog

July 17, 2025: The LHCP antenna is upgraded to version 2.1, using LDS technology, and has more stable performance than V2.
Sept. 15, 2025: The RHCP antenna is upgraded to version 2.1, using LDS technology, and has more stable performance than V2.

Key Features

Hexagonal shape for enhanced durability and a right-angle design for convenient fixation.
Ultrasonic welding technology for a lightweight yet secure antenna attachment.
Higher consistency in antenna gain to improve performance and stability.
